Consent
Informed Consent for Participation in a Research Study
You are invited to participate in a research study directed by Dr. John Paul Helveston of the Department of Engineering Management and Systems Engineering at George Washington University (GWU) and funded by the Department of Energy. Participation is entirely voluntary and you may obtain further information regarding this study by contacting us at gwuvehiclegroup7@gmail.com .
The purpose of this study is to identify the preferences and needs of car ownership in different communities. If you choose to participate in this study, you will be asked to answer an online survey about vehicle ownership and preference. The total amount of time you will spend on this study is 10 minutes. You may refuse to answer any of the questions and stop participating at any time.
Benefits : The most important reason why someone would like to participate in this study is that they can share their vehicle usage needs and help inform policies that decide incentives on EV ownership. You will not benefit directly from your participation in the study. However, the benefits to science and humankind that might result from this study include implementing electric vehicle subsidy policies that are more in tune with people’s requirements.
Concerns/Risks : You may not choose to volunteer for this study if you do not want to share information about your vehicle usage. Possible risks or discomforts you could experience during this study include: - Although very unlikely, there is a risk of email address information being compromised if it is shared and in case our systems are compromised. - Psychological stress could be caused by the time and effort spent answering the survey.
Confidentiality : Every effort will be made to keep your information confidential. However, this cannot be guaranteed. The data will be stored in a secured online database which only the PI and student researcher can access. If the results of this research study are reported in journals or at scientific meetings, the people who participated in this study will not be named or identified.
Additional Information : The Office of Human Research of George Washington University, at telephone number (202) 994-2715, can provide further information about your rights as a research participant.Your willingness to participate in this research study is implied if you proceed.

Great Work! Now that you have shared a bit about yourself, we’d like you to consider a scenario in which you can choose a car from a set of cars with different attributes.
Let’s learn about the attributes.
| Price - The final price paid for the vehicle in dollars, including all taxes and fees. | |
| Range - The maximum distance a vehicle can travel in a full tank/ fully charged battery. | |
| Mileage - The number of miles vehicle has traveled while in operation | |
| Operating Cost (Equivalent Gasoline Fuel Efficiency) - Cost in cents per mile driven of fueling the vehicle. The equivalent fuel efficiency in miles per gallon (MPG) of a conventional gasoline vehicle is displayed in parenthesis. (Assumes gasoline costs$3.30/gallon and electricity costs $0.16/kWh). | |
| Model Year - Model/Manufacturing year is the actual year the vehicle was built. |
| Types of Powertrain | Powertrain Definition |
|---|---|
| Conventional |
Gasoline engine only. |
| Hybrid (HEVs) |
Smaller gasoline engine + electric motor + small battery. Gasoline engine recharges the battery, fuel consumption is reduced |
| Plug-in Hybrid (PHEVs) |
Hybrid that can also be plugged in to an electrical outlet to charge the battery. Runs on electricity for a short range (10 – 40 miles), then switches to gasoline |
| Electric (BEVs) |
Electric motor only. Must be plugged into an electrical outlet to be refueled |
